In one embodiment, area to be targeted is rectangle, then positioning signal maximum transmitted length is the catercorner length of the rectangle,
Maximum transmission time can be acquired according to the spread speed of positioning signal S.Then, into data back period Tb, base is respectively positioned
After the record location signal S that stands reaches the temporal information of itself, the time need to be returned to its corresponding each isochronous controller SYNC
Information, in one embodiment, return data further include the identity information of locating base station itself, so that corresponding synchronously control
Device SYNC learns the temporal information received from which locating base station.The data back period, Tb was divided into n data back
Sub-period is respectively corresponded and is in from the different locating base stations of an interface of isochronous controller SYNC connection, above-mentioned locating base station
In same data back link, the conflict in transmission process in order to prevent, each data back sub-period only returns the data
Return the return data of the corresponding locating base station of sub-period.As shown in Fig. 2, data back sub-period Tb1 corresponds to locating base station
Bsam-1 and locating base station BSb2-1, it will be appreciated by those skilled in the art that the data of locating base station are only back to and the positioning
In first isochronous controller of base station connection, the isochronous controller is not passed the data to the isochronous controller of upper level
Defeated, therefore, locating base station Bsam-1 and locating base station BSb2-1 are in different data back links, can be shared same
Data back sub-period Tb1, and not will cause data transmission conflict.Locating base station Bsam-1 and locating base station BSb2-1 are in number
According to passback sub-period Tb1 during, the corresponding interface for the isochronous controller that respective return data is transmitted separately to be attached thereto.
Data back sub-period Tb2 corresponds to locating base station Bsam-2 and locating base station BSb2-2, locating base station Bsam-2 and locating base station
The return data of BSb2-2 passes through the locating base station Bsam-1 being attached thereto respectively and is transmitted to synchronous control with locating base station BSb2-1
The corresponding interface of device processed.Similarly, data back sub-period Tbn corresponds to locating base station Bsam-n and locating base station BSb2-n, fixed
The return data of position base station Bsam-n and locating base station BSb2-n passes through the locating base station Bsam- (n-1) ... being attached thereto respectively
Bsb2-1 is transmitted to the corresponding interface of isochronous controller by Bsam-1 and locating base station Bsb2- (n-1) ....Until isochronous controller
After SYNC receives the return data of connected all locating base station BS, terminate data back period Tb.Synchronously control
The return data of each locating base station received is sent to location-server LS again by device SYNC.
